**SQL Query Description**
|
|
==========================
|
|
|
|
This SQL query retrieves specific data from the `Process` table based on certain conditions and formats the output.
|
|
|
|
### Query Breakdown
|
|
|
|
#### 1. Select Statement
|
|
|
|
The query selects all columns (`*`) from the `Process` table, but only for rows that meet the specified conditions.
|
|
|
|
```markdown
|
|
SELECT Left$([PartNumber],7) AS prt, Right$([PartNumber],1) AS Rev, Process.*
|
|
```
|
|
|
|
- `Left$([PartNumber],7)` extracts the first 7 characters from the `PartNumber` column and assigns it to a new column named `prt`.
|
|
- `Right$([PartNumber],1)` extracts the last character from the `PartNumber` column and assigns it to a new column named `Rev`.
|
|
- `Process.*` selects all columns (`*`) from the `Process` table.
|
|
|
|
#### 2. WHERE Clause
|
|
|
|
The query filters rows based on two conditions:
|
|
|
|
```markdown
|
|
WHERE (((Process.MetalType)=[Forms]![Utilization]![Combo12]) AND ((Left$([PartNumber],1))="9" Or (Left$([PartNumber],1))="8" Or (Left$([PartNumber],1))="7"))
|
|
```
|
|
|
|
- `((Process.MetalType)=[Forms]![Utilization]![Combo12])` filters rows where the value in the `MetalType` column matches the value in the `Combo12` field of the `Utilization` form.
|
|
- `(Left$([PartNumber],1))="9" Or (Left$([PartNumber],1))="8" Or (Left$([PartNumber],1))="7"` filters rows where the first character of the `PartNumber` column is either "9", "8", or "7".
|
|
|
|
#### 3. INTO Clause
|
|
|
|
The query creates a new table named `[Util Selection 1]` to store the filtered data.
|
|
|
|
```markdown
|
|
INTO [Util Selection 1]
|
|
```
|
|
|
|
#### 4. ORDER BY Clause
|
|
|
|
The query sorts the output by two columns:
|
|
|
|
- `Left$([PartNumber],7)` sorts the values in ascending order based on the first 7 characters of the `PartNumber` column.
|
|
- `Right$([PartNumber],1)` sorts the values in descending order based on the last character of the `PartNumber` column.
|
|
|
|
```markdown
|
|
ORDER BY Left$([PartNumber],7), Right$([PartNumber],1) DESC;
|
|
```
|
|
|
|
This ordering means that rows with more characters at the beginning (`Left`) will come first, and rows with different characters at the end (`Right`) will be sorted in descending order.
